Nervous about taking assembly

I have been out of teaching for over three years and am currently doing a 2 day a week teaching job. I have to do a 20 minute assembly and am a bit nervous - I haven't done one for 5 plus years. I know the content I am doing but it's just the standing up in front of children/teachers bit.

I used to enjoy taking assembly. Two tips: try to speak from memory so you are not reading notes, that way you can look directly at the children and move around so they have to watch you and don't know what to expect. I also used to like picking children to help hold things or act out parts, they used to behave well in the hope of getting picked. This was for KS1 assembly so might not apply if you have older children.

If using slides, use a USB clicker so you don't nee to stand next to the laptop, you can then pace around a bit and feel a little easier. Getting up and getting their attention is the hardest bit. Once you've got them, you're in.
